the new.qcow2 like following:
# qemu-img info new.qcow2
image: new.qcow2
file format: qcow2
virtual size: 2.0G (2097152000 bytes)
disk size: 748M
cluster_size: 65536
so, my question is why the image size increased after my operation?
thanks.

the other question: when I change the buffer size #define IO_BUF_SIZE 32768
to #define IO_BUF_SIZE (1 * 1024 * 1024), the savevm is more quickly.

the cache allocate on host for disk file image by qemu?
